Biometria, morfometria, conformação e acabamento de carcaça de cabritos (Boer x SRD), terminados em pastagem nativa e submetidos a diferentes níveis de suplementação.

Abstract

The present work had as objective evaluates the biometry, the corporal condition and the morfometria of the carcass of kid goats Fl (Boer X SRD), finished in native pasture and submitted at different supplementation levels. The work was driven in the farm belonging Nupearido the Federal University of Campina Grande (UFCG), in Patos - PB. 24 were used kids goats, distributed in a completely randomized design with four treatments (supplemented with 0,0; 0,5; 1,0 and 1,5% of the alive weight in matter dry) and six repetitions. The measures biometrics and the corporal condition were accomplished in the beginning and in the end of the experiment the measures morfometricas were already checked after the discount of the animals according to RIISPOA. The data were submitted to the variance analysis and of regression, always at the level of 5% of significancy. There was positive lineal effect of the supplementation for width of the croup, circunference of the thigh and scrotal circumference. It was observed that the corporal scores (back and external) they grew lineally (P <0,05) with the supplementation. For the carcass lineal and positive effect was observed for the depth and the thoracic width, as well as for the score of the resignation and of the pelvic-renal fat. The growing use of levels of supplementation allowed to esteeming larger width of the croup and the perimeters of the leg and of the scrotum, and that the increase of the supplementation allows the obtaining of animals with larger scores of corporal condition. The supplementation also allowed esteeming larger sizes for the width and thoracic depth, as well as carcasses with better resignation and larger amounts of energy reservations in his/her interior. I f the objective will obtain heavier carcasses originating from of animals with weight around 28,42 kg of PV with measured larger biometrics, good corporal condition, deeper and wide carcasses and with larger deposits of energy reservations the recommended level is of 1,5% of PV, but i f the purpose will obtain lighter carcasses the supplementation level can be smaller.
